There would be no need to decrement later people because they're definitely referred to using pointers. You'd just need to update the previous person's pointer to the new next person.
If it's a numeric ID (0-255) assigned to each person in the group, you'd either need to decrement later people or assign based on some kind of lowest available method, in which case you'd get kinda funny UX when new-member-Jerry can be #3 on the list because he's taking over for old-member-Gerry, or he can be #255 because that's the last spot.
If we're talking about pointers, I assume you mean a collection with up to 256 of them. In which case, there are plenty of collection data structures out there that wouldn't really have a hard limit (and if you go with a basic array, wouldn't that have a size limit of far more than 256 natively on pretty much any language?)
